From what I can remember seeing, mfg. made rifles with a trap door mag. I. have never liked the trap door, have always liked the detachable mag. However, in the past, it always seemed you were stuck with the trap door mag. I, have noticed with in the passed several years, more and more mfg. are comming out with detachable mags. What do you guys think about this. .I, made a mistake the title should read, Detachable mag. vs trap door. Ok, ,I did not know what, I was refering to was called a mag. with a trap door. Then trapdoor vs. detatchable mag.
